Antilock Brake System
(ABS)
How does ABS work?
The maximum braking force that
can be transferred to the road is
partially dependent on the co-
efficient of friction of the road.
Gravel, ice, snow and wet roads
offer a considerably lower coeffi-
cient of friction than a dry, clean
asphalt surface. The poorer the
coefficient of friction of the road
is, the longer the braking dis-
tance will be.
If the maximum transferable
brake pressure is exceeded when
the driver increases the brake
pressure, the wheels begin to
lock and driving stability is lost;
this could result in a fall. Before
this situation occurs, ABS is
activated and the brake pressure
is adjusted to the maximum
transferable braking force. This
enables the wheels to continue
to turn and maintains driving
stability regardless of the road
surface condition.
What happens when
rough roads are
encountered?
Rough roads can briefly lead to
a loss of contact between the
tires and the road surface. The
transferable braking force is then
reduced to zero. If braking is car-
ried out in this situation, ABS
must reduce the brake pressure
to ensure driving stability when
restoring contact to the road.
At this point in time, ABS must
assume extremely low friction
coefficients (gravel, ice, snow)
so that the wheels turn in every
imaginable case and driving sta-
bility is ensured. After detecting
the actual conditions, the system
adjusts the optimum brake pres-
sure.
Lifting off rear wheel
During extremely heavy and rapid
decelerations it is possible that
the BMW Motorrad ABS can-
not prevent the rear wheel from
lifting off the ground. In these
cases, the motorcycle can also
flip end over end.
WARNING
Lifting off of the rear wheel
due to heavy braking
Accident hazard
When braking heavily, bear in
mind that the ABS control can-
not always be relied on to pre-
vent the rear wheel from lifting
off the ground.
